Complete RaS 437 Meteorite

This complete individual of Ramlat as Sahmah (RaS) 437 is one of several stones totaling 2 kg. RaS 437 is from an area in Oman where a relatively large number of meteorites have been found, as they are more readily identifiable in certain desert environments. RaS 437 experienced extreme thermal metamorphism on its parent asteroid: its once-spherical chondrules were extensively recrystallized and the mineral grains within the rock (which initially had diverse compositions) became chemically uniform. The small amount of water that the meteorite initially contained was largely baked out the rock
